Questions about oxalic acid drizzling

High, I have a few questions about oxalic acid.
1. Can drizzling with oxalic acid bring down a 12 % mite infestation?
2. Should there be little or no brood when I drizzle?
3. Is drizzling with oxalic acid more harmful than treating with formic acid?
4. Is oxalic acid drizzling temperature dependent?
5. What strength should the mixture be?
6. Should the syrup be 1:1 or 2:1 or something else?
7. How much should I drizzle on them?
8. Do I drizzle into both supers?
9. Do I drizzle onto or between the frames?

Re: Questions about oxalic acid drizzling

A one time drizzle of OA works best on broodless bees as it does not get the mites in the capped brood. From what I have read the bees tolerate it very well once but it is very harmful if repeated on those bee. What does that say about a second year queen? Read Randy Olivers research.

Re: Questions about oxalic acid drizzling

I used oxalic acid dribble last fall and it worked well for me. It is only recommended to do one time, and works best at low brood times. It is not temperature dependant. That is one reason I chose it. The concentrations and directions I used are at www.scientificbeekeeping.com as mentioned above. You will need a kitchen scale to correctly weigh your materials, and I used a large livestock syringe. Sure got a good mite kill. Good luck to you!
